Visualization of Network Security Events

This thesis focuses on visualization of network security events via modern web technologies. Multiple technologies for creating modern web application supporting visualising large volume of security events were studied. The application was designed for NEMEA system which thanks to this thesis acquired graphical user interface allowing big data visual analysis. Visualized events allow drill-down analysis. The application operates on security events stored in IDEA format which is used among other network security services and the application is therefore transferrable to them. NEMEA Dashboard has been tested on the target group of network administrators using acceptance tests
